Specification of Letters Patent.

Patented Feb. 4, 1919.

To all 107mm it may concern:

Be it known that I, JOHN W. Cosenovn, a citizen of the United States, residing at Medford, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Sole-Holders, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to holders for piles of blanks and is herein illustrated in connection with sole holders for use in the manufacture of boots and shoes.

In the manufacture of certain kinds of boots and shoes it is customary to cement a I tap to the sole preparatory to sewing the two together. Commonly a pile of soles with the taps freshly cemented thereto is sub ected to pressure for a time sufiicient to permit the cement to dry or set. It is desirable to provide for this operation a'press and a plurality of small holders each of which may be filled, placed in the press and, after having been subjected to pressure, removed therefrom and allowed to stand until the cement has set. The pressure imparted by the press should, of course, be maintained by the holder.

One feature of the present invention comprises a holder for a pile of blanks having, in combination, two members slidable with respect to each other, and a locking bar loosely carried by one member and adapted,

when force is applied, to separate the members, to lock said members from separating movement. In the illustrative device one memberis a U-shaped frame upon the arms P n out in the ppended claims.

; Referring now to the accompanying draw- 1ngs,--

Figure 1 is a plan of a device in which the present invention is embodied, and

Fig. 2 is a longitudinal vertical section of the device showing a pile of blanks in position.

The frame of the device is a U-shaped member having upright arms 3, upon which is slidable a clamping member in the form of a block 5 having slots to receive the arms. The block is hollowed out to form a chamber 7 which opens upon the inner sides of the arms, the right-hand end of the block being cut out as shown for a purpose presently to be described. Loosely mounted in the block is a locking bar 9 of a length greater than the distance between the arms 8, said bar lying in an inclined position with one end resting against the inner side of one arm of the frame and the other end resting against the inner side of the other arm. In order to facilitate the unlocking of the bar, there is formed on the higher end a yoke, one arm of which is indicated at 119, which straddles the right-hand arm 3 of the frame and is accessible to the operator by reason of the recess or cut out portion of the block 5.

With the construction thus far described, it will be apparent that the block 5 may be moved freely downward to cause the pile of blanks 100 to be compressed, but that when force is exerted to move the block upward to separate the frame and block, the bar will bind between the arms and prevent such movement.

In order to insure that this binding effect shall take place as quickly as possible, as well as to maintain the block 5 in raised position preparatoryto inserting the pile of blanks a spring 11. the upper end of which extends into asocket in the member 5, bears with its lower end againstthe bar 9 at a point near its higher end. If now the block is raised, in a'manner presently to be described, the spring will cause'suificient binding of the bar between the arms 3 to cause the block to remain wherever it is positioned so that the operator may remove and replace the pile of blanks. At the same time any considerable force exerted downwardly upon the block will readily depress it. When the block has been forced down to exert the desired pres sure upon the pile of blanks, and the force is removed, the compressed pile exerts a force upwardly. The spring 11, under these circumstances, tends to hold the right hand end of the locking bar 9 practically stationary at its point of contact with the righthand arm 3 while the left-hand end of the bar is raised slightly until the bar binds tightly between the arms and further upward movement of the block 5 is prevented. By properly proportioning the parts, this upward movement due to the compressed blanks may be made practically negligible. In order to release the locking bar at any time it is merely necessary to increase its inclination; and in the illustrative device this is accomplished by lifting up the right-hand end either by pressing upwardly with the fingers on the fork 119 or by using a wrench 13 as indicated by broken lines.

In order to compensate for shortening of the bar 9 due to wear, a gib 15 adjustable by screw bolts 17 may he provided in one or in both slots in the block 5.

In the operation of the device the pile of blanks is placed in the holder between two boards 19, as shown, and the block 5 pushed down upon the top board. The device is then placed in a press and pressure applied, after which the pressure of the press is removed and the device with the compressed soles in it taken out and allowed to stand until the cement has set. At that time the locking bar is released, and the blanks removed and replaced.

Although the invention has been described in connection with a particular device, it should be understood that the invention is not limited in the scope of its application to the particular device which has been shown and described.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A holder for a pile of blanks having, in combination, two members slidable with respect to each other, one of said members having substantially parallel arms, and a locking bar carried by the other member, said bar being of a length greater than the distance between the arms.

.2. A holder for a pile of blanks, having, in combination, two members vertically slidable toward each other, and a locking bar inclined to the horizontal loosely carried by one member and engaging the other with portions near its opposite ends, whereby when force is applied to the members to separate them, the angle of inclination of the bar to the horizontal is changed to cause said bar to bind.

3. A holder for a pile of blanks having, in combination, a U-shaped frame, a clamping member slidable on the arms of the frame, and a locking bar loosely mounted in the clamping member and of a length greater than the distance between the arms.

4. A holder for a pile of blanks having, incombination, a U-shaped frame, a clamping member slidable on the arms of the frame, a locking bar loosely mounted in the clamping member and of a length greater than the distance between the arms, and a spring between the clamping member and the bar.

5. A holder for a pile of blanks having, in combination, a U-shaped frame, a clamping block slidable on the arms of the frame, and a locking bar loosely .mounted in'the block and of a length greater than the distance between the arms.

6. A holder for a pile of blanks having,

in combination, a U-shaped frame, a clamping block slidable on the'arms of the frame, a locking bar loosely mounted in the block and of a length greater than the distance between the arms, and a spring between the said bar being of a length greater than the distance between the arms and occupying an inclined position with its ends resting against said arms.

8. A holder for a pile of blanks having, in

combination, a U-shaped frame, a clamping member slidable onthe arms of. the frame, and a locking bar carried by said member, said bar being of a length greater than the distance between the arms and occupying an inclined position with its ends resting against said arms, and a spring acting upon said bar near the higher end thereof.

9. A holder for a pile of blanks, having,

in combination, a U-shaped frame, a clamping member slidable on the arms of the frame, said member having a chamber there in which opens upon the inner sides of the arms, and a locking bar in said chamber of a length greater than the distance between the' arms,- said-bar contacting at one end with the inner side of one arm and at the other with the inner side of the other arm.

10. A holder for a pile of blankshaving, in combination, a U-shaped frame, a clamp ing member slidable on the arms of the frame, said member having achamberthere' in which opens upon the inner sides of the arms, a locking bar in said chamber of a length greater than the distance between the arms, said bar contacting at one end with the inner side of one arm and at the other with the inner side of the other arm, and a spring acting upon the bar at a point nearer one end than the other of said bar.

11. A holder for a pile of blanks having, in combination, a U-shaped frame, a clamping member having slots to receive the arms 10 of the frame, a locking bar carried by said member of a length greater than the distance between said arms, a gib in one of said slots, and means whereby said gib may be adjusted to compensate for Wear of said bar. 5

In testimony whereof I have signed my name to this specification.
